Given:

A car is driving at a velocity of 24 m/s. Its brakes can supply an acceleration of -7 m/s².

To find:

Time taken to bring the car to a stop?

Calculation:

Let final Velocity be "v" , initial velocity be "u" , acceleration be "a" and time taken be "t":

Applying the 1st equation of kinematics , considering the acceleration to be constant:

 \sf \therefore \: v = u + at

 \sf  =  >  \: 0= 24+ ( - 7)t

 \sf  =  >  \: 0= 24 - 7t

 \sf  =  >  \: 7t= 24

 \sf  =  >  \: t = 3.42 \: sec

So, time taken for the car to stop is 3.42 seconds.
